From Integrated To Expedient

Study draws on experiences in the catchment of the Great Ruaha River in Tanzania.

This book takes a two-staged approach to contribute to the contemporary Integrated Water Resources Management (IWRM) research. First it investigates sub-basin-scale IWRM modelling and scenario planning. The Jordanian Wadi Shueib is used as exemplary case study. Then, it develops a framework to collaboratively manage planning and decision making knowledge on the basis of semantic web technologies. Future IWRM initiatives can benefit from the valuable insights achieved in the presented study.

Progressive agricultural and water development in the Krishna Basin in South India has led to a rising over commitment of water resources and signs of basin closure are apparent during dry periods. As human consumptive uses are approaching the limits of water availability, this report focuses on the Lower Krishna Basin that bears the brunt of any intervention upstream. Capturing the process of basin closure requires an understanding of the political dimension of access to water and the scope for change. As basin closure intensifies the interconnectedness of ecosystems and water users, adjustments and management decisions result in spatial re-appropriation of water and basin-wide strategies for water management and development that start with the definition and the implementation of water allocation mechanisms are increasingly needed.

Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were estimated for each sector and the economic cost of failing to provide water was predicted. For the future scenarios, the impact of infrastructure development and water conservation measures were assessed. The study illustrates how a relatively simple model can provide useful insight for resource planning and management.

Increasing income and urbanization are triggering a rapid change in food consumption patterns in India. This report assesses India’s changing food consumption patterns and their implications on future food and water demand. According to the projections made in this study, the total calorie supply would continue to increase, but the dominance of food grains in the consumption basket is likely to decrease by 2050, and the consumption of non-grain crops and animal products would increase to provide a major part of the daily calorie supply. Although the total food grain demand will decrease, the total grain demand is likely to increase with the increasing feed demand for the livestock. The implications of the changing consumption patterns are assessed through consumptive water use (CWU) under the assumptions of full or partial food self-sufficiency.

In the face of growing water stress and increasing concerns over the sustainability of water use, Tanzania has, in common with many other countries in Africa, focused largely on the development of more integrated catchment-wide approaches to water management. In the Great Ruaha River Basin, considerable effort has gone into increasing water productivity and the promotion of mechanisms for more efficient allocation of water resources. Over a period of five years, the RIPARWIN project investigated water management in the basin and evaluated the effectiveness of some of the mechanisms that have been introduced. The study findings are relevant to basins in developing countries where there is competition for water and irrigation is one of the main uses.

Redefining Diversity and Dynamics of Natural Resources Management in Asia, Volumes 1-4 brings together scientific research and policy issues across various topographical area in Asia to provide a comprehensive overview of the issues facing the region. Sustainable Natural Resources Management in Dynamic Southeast Asia, Volume 1, pulls together regional experts in the field to look specifically at sustainability issues across the region, to see what has been implemented, what the impacts have been, and what other options are available. In the race to be a developed region, many Southeast Asian countries have foregone natural resources through haphazard use. As a result, the people are faced with numerous environmental challenges, particularly deforestation and forest degradation, biodiversity loss and ecosystem degradation, reduction in soil quality, and decreases in the quantity of available water. Community-based forest management is the involvement of local communities in the protection, conservation and management of public forests to prevent degradation through sustainable practices while still responding to the basic social and economic needs of local populations. When the people who depend on forest resources for their livelihoods are jointly responsible for managing and protecting them, they tend to do so in a more sustainable manner by focusing on the long-term benefits rather than the immediate short-term gains. However, when tenure rights are weak, unclear, or insecure, or offer limited benefits, people are incited in extracting more immediate benefits, resulting in suboptimal forest management and the reduction of carbon stocks. Features case studies that cover issues such as rising levels of deforestation, forest degradation, regional food security, ecosystem degradation, biodiversity loss, conflicts over natural resource use, water management issues, and impacts on local communities Includes contributions from local researchers who are dealing with these issues first hand, and on a daily basis Includes a comparative review on REDD+ implementation in different communities Focuses on sustainability issues across the region
